8 SECTION 1. INTRODUCTION 1-1. PRESSURE FRYER The Henny Penny Pressure Fryer is a basic unit of food processing equipment. It has found wide application in institutional and commercial food service operations. P-H-T Pressure Heat Time A combination of pressure, heat, and time is automatically controlled to produce the optimum in a tasty, appealing product. Pressure is basic to this method of food preparation. This pressure is developed from the natural moisture of the food. The patented lid traps this moisture and uses it as steam. Because the steam builds rapidly, the greater part of the natural juices are retained within the food. An exclusive deadweight assembly vents excess steam from the pot and maintains constant low, live steam pressure. Heat generated is another important factor of the pressure fryer. The normal suggested frying operation is between 315 and 325 F. This results in energy savings and extends the frying life of the shortening. Energy savings is realized due to the unit s short frying time, low temperature, and heat retention of the stainless steel frypot. Time is important because the shorter the time involved in frying foods results in additional economies for the user. Foods are table ready in less time than it would take to fry them in a conventional open-type fryer. As of August 16, 2005, the Waste Electrical and Electronic Equipment directive went into effect for the European Union. Our products have been evaluated to the WEEE directive. We have also reviewed our products to determine if they comply with the Restriction of Hazardous Substances directive (RoHS) and have redesigned our products as needed in order to comply. To continue compliance with these directives, this unit must not be disposed as unsorted municipal waste. For proper disposal, please contact your nearest Henny Penny distributor PROPER CARE 1-3. ASSISTANCE As in any unit of food service equipment, the Henny Penny Pressure Fryer does require care and maintenance.

10 SECTION 2. INSTALLATION 2-1. INTRODUCTION This section provides the installation instructions for the electric and gas models of Henny Penny Pressure Fryers. Installation of this unit should be performed only by a qualified service technician. Do not puncture the fryer with any objects such as drills or screws as electrical shock or component damage could result UNPACKING INSTRUCTIONS The fryer is shipped bolted to a wooden base and covered with a cardboard container. Both gas and electric models are shipped completely assembled. If ordered, optional casters are packaged and shipped separately. 1. Cut the band from around the bottom of the carton. Any shipping damage should be noted in the presence of the delivery agent and signed prior to his or her departure. 2. Lift the carton from the fryer. Step 2 3. Open the lid of the fryer and remove the basket plus all accessories. 4. Lay the fryer on its side, resting it in supports. Take care when moving the fryer to prevent personal injury. The fryer weighs approximately 300 lbs. (136 kgs). Step

11 2-2. UNPACKING INSTRUCTIONS (Continued) Cap 5. Remove the four leg bolts from the wooden shipping base. Remove and discard the wooden base. 6. Thread the shipping bolts back into the legs to provide leveling adjustment feet. If ordered, install casters into the legs, with the locking casters in front. 7. Place fryer in an upright position. 8. Prepare the deadweight assembly for operation: Step 8 The metal shipping support is placed within the deadweight assembly housing to protect the deadweight orifice and deadweight during shipment. This support must be removed prior to installation and start-up. a. Unscrew the deadweight cap. b. Remove the round deadweight. c. Remove and discard the shipping support. d. Clean the deadweight orifice with a dry cloth. e. Replace the deadweight and secure the deadweight cap. 9. Open lid and remove packing and racks from inside of frypot. 10. Remove the protective paper from the fryer cabinet. It is necessary to clean exterior surface with a damp cloth

12 2-3. SELECTING THE FRYER LOCATION The proper location of the fryer is very important for operation, speed, and convenience. Choose a location which will provide easy loading and unloading without interfering with the final assembly of food orders. Operators have found that frying from raw to finish, and holding the product in a warmer provides fast continuous service. Landing or dumping tables should be provided next to at least one side of the fryer. Keep in mind the best efficiency will be obtained by a straight line operation, i.e., raw in one side and finish out the other side. Order assembly can be moved away with only a slight loss of efficiency. To properly service the fryer, 24 inches (60.96 cm) of clearance is needed on all sides of the fryer. Access for servicing can be attained by removing a side panel. Also, at least 6 inches (15.24 cm) around the base of the gas units is needed for proper air supply to the combustion chamber. To avoid a fire, install the gas fryer with minimum clearance from all combustible and noncombustible materials, 6 inches (15.24 cm) from side and 6 inches (15.24 cm) from back. If installed properly, the gas fryer is designed for operation on combustible floors and adjacent to combustible walls. To avoid fire and ruined supplies, the area under the fryer should not be used to store supplies. To prevent severe burns from splashing hot shortening, position and install fryer to prevent tipping or movement. Restraining ties may be used for stabilization LEVELING THE FRYER For proper operation, level the fryer from side to side and front to back, using level on the flat areas around the frypot collar. FAILURE TO FOLLOW THESE LEVELING INSTRUCTIONS CAN RESULT IN SHORTENING OVERFLOWING THE FRYPOT WHICH COULD CAUSE SERIOUS BURNS, PERSONAL INJURY, FIRE, AND/OR PROPERTY DAMAGE

13 2-5. VENTILATION OF FRYER The fryer must be located with provision for venting into adequate exhaust hood or ventilation system. This is essential to permit efficient removal of the flue gases and frying odors. Special precaution must be taken in designing an exhaust canopy to avoid interference with the operation of the fryer. We recommend you consult a local ventilation or heating company to help in designing an adequate system. Ventilation must conform to local, state, and national codes. Consult your local fire department or building authorities. When installing the gas fryer do not attach an extension to the gas flue exhaust stack. This may impair proper operation of the burner, causing malfunctions and possible negative backdraft

14 2-6. GAS SUPPLY The gas fryer is factory available for either natural or propane gas. Check the data plate on the right side panel of the cabinet to determine the proper gas supply requirements. The minimum supply for natural gas is 7 inches water column (1.7 kpa), and 10 inches water column (2.49 kpa) for propane. Maximum gas supply is 14 inches water column (3.49 kpa, or.5 psi. Do not attempt to use any gas other than that specified on the data plate. Conversion kits can be installed by your distributor if required. Incorrect gas supply could cause an explosion or fire resulting in severe injuries and/or property damage

15 2-7. GAS PIPING Please refer below for the recommended hookup of the fryer to main gas line supply. To avoid possible serious personal injury: Installation must conform with American National Standard Z223.1-Latest Edition National Fuel Gas Code and the local municipal building codes. In Canada, installation must be in accordance with Standard CSA Bl49-1&2, Installation Codes Gas Burning Appliances and local codes. In Australia, installation must conform to Australian requirements. The fryer and its manual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kpa) (34.47 mbar). The fryer must be isolated from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.45 kpa) (34.47 mbar). A standard 1/2 inch, black steel pipe and malleable fittings should be used for gas service connections. Do not use cast iron fittings. Although 1/2 inch size pipe is recommended, piping should be of adequate size and installed to provide a supply of gas sufficient to meet the maximum demand without undue loss of pressure between the meter and the fryer. The pressure loss in the piping system should not exceed 0.3 inch water column (0.747 mbar). Provisions should be made for moving the fryer for cleaning and servicing. This may be accomplished by: 1. Installing a manual gas shutoff valve and a disconnect union, or 2. Installing a heavy duty design A.G.A. certified connector which complies with the Standard for Connectors for Moveable Gas Appliances, ANSI Z21.6, or CAN/CSA 6.16 with a quick disconnect coupling

16 2-7. GAS PIPING (Henny Penny Part No ), which complies with (Continued) ANSI standard Z21.41, or CAN Also adequate means must be provided to limit the movement of the fryer without depending on the connector and quickdisconnect device or its associated piping to limit the fryer movement. 3. See the illustration on following page for the proper connections of the flexible gas line and cable restraint. The cable restraint limits the distance the fryer can be pulled from the wall. For cleaning and servicing the fryer, the cable must be unsnapped from the unit and the flexible gas line disconnected. This will allow better access to all sides of the fryer. The gas line and cable restraint must be reconnected once the cleaning and servicing is complete

17 2-7. GAS PIPING (Continued)

18 2.8 GAS LEAK TEST Prior to turning the gas supply on, be sure the gas valve knob on the gas control valve is in the OFF position. After the piping and fittings have been installed, check for gas leaks. A simple checking method is to turn on the gas and brush all connections with a soap solution. If bubbles occur, it indicates escaping gas. In this event, the piping connection must be redone. To avoid fire or explosion, never use a lighted match or open flame to test for gas leaks. Ignited gas could result in severe personal injury and/or property damage GAS PRESSURE REGULATOR SETTING The gas pressure regulator on the automatic gas valve is factory set as follows: Natural: 3.5 inches water column (0.87 kpa) Propane: 10.0 inches water column (2.49 kpa) The gas pressure regulator has been set by Henny Penny and is not to be adjusted by the user GAS PILOT & BURNER LIGHTING AND SHUTDOWN PROCEDURE Lighting Procedure - Solid State Ignition 1.

Turn main power switch to OFF position. 4. Turn the gas valve knob counterclockwise to the OFF position. (OFF pointed down) 5. Wait a sufficient length of time (at least 5 minutes) to allow any gas which may have accumulated in the burner compartment to escape 6. Turn the gas valve knob clockwise to the ON position. Step 4 (ON pointed down)

19 2-10. GAS PILOT & BURNER LIGHTING AND SHUTDOWN PROCEDURE (Continued) 7. Turn main power switch to ON position. 8. Wait about 45 seconds for the burner to light. 9. Listen for the gas burner ignition. It will be an audible sound due to the gas igniting at the gas jets within the burner. 10. The burner lights and operates until the shortening temperature reaches a preset temperature, and lights. Do not leave the burner on for more than 10 seconds without shortening in the frypot or damage to the frypot may result. Shutdown Procedure 1. Turn main power switch to OFF position. 2. Turn the gas valve knob counterclockwise to the OFF position PILOT FLAME ADJUSTMENT The pilot flame is preset at the factory. If adjustment is necessary, contact your local independent Henny Penny distributor PRESSURE REGULATOR ADJUSTMENT (GAS ONLY) The gas regulator is preset at the factory at 3.5 inch water column (0.87 kpa) for natural gas (10.0 inch (2.49 kpa) for propane). If adjustment is necessary, contact your local independent Henny Penny distributor

33 3-3. FILLING OR ADDING SHORTENING The shortening level must always be at the frypot level indicator on the rear of the frypot (see photo on next page). Failure to follow these instructions could result in a fire and/or damage to the fryer. When using solid shortening, it is recommended to melt the shortening on an outside heating source before placing it in the frypots. The elements on electric fryers, or the frypot surface on gas fryers, must be completely submerged. Fire or damage to the frypot could result. 1. It is recommended that a high quality frying shortening be used in the fryer. Some low grade shortenings have a high moisture content and will cause foaming and boiling over. To avoid severe burns when pouring hot shortening into frypot, wear gloves and take care to avoid splashing. 2. The electric model 500 requires 48 lbs. (21.8 kg) of liquid shortening, and the gas model requires 43 lbs. (19.5 kg). Model 500 fryers have 2 level indicator lines inscribed on the rear wall of the frypot, whereas the model 600 has only 1 level indicator. The level indicator lines show the proper shortening levels. 3. Cold shortening should be filled to 1/2-inch (12.7 mm) below a single level indicator line, and frypots with 2 level indicator lines, cold shortening should be even with the lower level indicator line. The shortening expands when heated and should be at the level indicator line when the shortening is hot, or the top level indicator line on model 500s

34 3-4. CARE OF THE SHORTENING FOLLOW THE INSTRUCTIONS BELOW TO AVOID SHORTENING OVERFLOWING THE FRYPOT, WHICH COULD RESULT IN SERIOUS BURNS, PERSONAL INJURY, FIRE, AND/OR PROPERTY DAMAGE. 1. Frying breaded food products requires frequent filtering to keep the shortening clean. The shortening should be filtered after every 3 to 6 Cook cycles. For the best quality product, Do not exceed 6 Cook Cycles without filtering. Refer to Filtering of Shortening Section. 2. Maintain the shortening at the proper cooking level. Add fresh shortening as needed. 3. Do not overload the baskets with product (12 lbs. (5.4 kg.) for model 600 fryers and 14 lbs (6.4 kg.) for model 500 fryers, or place product with extreme moisture content into baskets. WITH PROLONGED USE, THE FLASHPOINT OF SHORTENING IS REDUCED. DISCARD THE SHORTENING IF IT SHOWS SIGNS OF EXCESSIVE SMOKING OR FOAMING, OR SERIOUS BURNS, PERSONAL INJURY, FIRE, AND/OR PROPERTY DAMAGE COULD RESULT

35 3-5. BASIC OPERATIONS AND PROCEDURES These are just basic procedures. Refer to Wendy s operating procedures for more detailed instructions. 1. Be sure the drain valve is in the closed position. 2. Remove fry basket from frypot and leave lid up. 3. Fill the frypot with shortening. VALVES CLOSED (ELECTRIC) When using new shortening, it is recommended to melt the shortening on an outside source before placing shortening in the frypot. Unless elements are completely covered in shortening, fire or damage to the frypot could result. 4. Move power switch to the COOK position. Unit automatically goes into the Melt Cycle. When the temperature reaches 230 F (110 C) the control goes into the Heat Cycle, and heats the shortening until the temperature setting is reached. VALVES CLOSED (GAS) Bypass the Melt Cycle, if desired, by pressing a product button and holding it for 4 seconds. Do not bypass the Melt Cycle unless enough shortening has melted to completely cover all of the heating elements, or the curved surface of the gas frypot. If Melt Cycle is bypassed before these surfaces are covered, excessive smoking of the shortening or a fire will result. Step 8 5. Completely stir shortening to stabilize the temperature throughout the frypot. 6. If the shortening was not filtered the night before at shutdown, it should be filtered now, after the shortening reaches the frying temperature and before the fryer is used. Refer to Filtering of Shortening Section

36 3-5. BASIC OPERATIONS AND PROCEDURES (Continued) IF THE SHORTENING TEMPERATURE EXCEEDS 420 F (216 C), IMMEDIATELY SHUT OFF THE POWER AT THE MAIN CIRCUIT BREAKER AND HAVE THE FRYER REPAIRED. IF SHORTENING TEMPERATURE EXCEEDS ITS FLASHPOINT, FIRE WILL OCCUR, RESULTING IN SEVERE BURNS AND/OR PROPERTY DAMAGE. 6. Once the shortening temperature has stabilized at the set-point temperature and is lit, place the baskets into the shortening. Then place product into the basket. Do not overload, or place product with extreme moisture content into the basket. 12 lbs. (5.4 kgs) for the models 500 and 600, is the maximum amount of product per frypot. Failure to follow these directions can result in shortening overflowing the frypot. Serious burns or damage to the frypot could result. Step 8 7. Lift the basket slightly out of the shortening and shake basket to separate pieces. 8. Remove basket handle and close lid quickly, latching the lid. 9. Tighten the lid spindle clockwise, sealing the lid. Align red knob on the spindle with red knob on the latch. Step 9 LATCH THE LID PROPERLY AND ALIGN THE RED BALLS OR SEVERE BURNS WILL RESULT

37 3-5. BASIC OPERATIONS AND PROCEDURES (Continued) 10. Press to start a Cook Cycle. The display counts down the cooking time. To check the shortening temperature press stop a Cook Cycle, press and hold. or to 11. Within a few minutes, the pressure gauge increases to the OPERATING ZONE. If it does not recheck the procedures and then refer to the troubleshooting section. 12. At the end of the Cook Cycle the fryer automatically depressurizes, an alarm sounds and the display flashes DONE. To stop the alarm, press. DO NOT ATTEMPT TO OPEN LID UNTIL THE PRESSURE DROPS TO ZERO. LID IS LOCKED WHEN FRYER IS UNDER PRESSURE. DO NOT ATTEMPT TO FORCE THE LID LATCH OR OPEN THE LID WHILE UNDER PRESSURE. OPENING THE LID WHEN THE FRYPOT IS PRESSURIZED ALLOWS HOT SHORTENING AND STEAM TO ESCAPE FROM THE FRYPOT, RESULTING IN SEVERE BURNS. 13. After pressure drops to zero, turn the spindle counterclockwise. Do not flip or spin the spindle cross arm when opening the lid because it could damage the acme nut inside the cross bar. 14. Unlatch and raise the lid quickly to allow most of the condensation on the lid to drain through the drain channel and not into the shortening. Do not let the lid slam up against the backstop cause damage to the hinge could result. Step Using the detachable handle, lift the basket and hang it on the side of the frypot to drain. Dump product into holding pan

38 3-6. REGULAR MAINTENANCE SCHEDULE Procedure Filtering of shortening Filter pump problem prevention Changing of shortening Changing the filter envelope Cleaning the frypot Cleaning the deadweight valve Night closing procedures Check optional rinse hose for deterioration Reversing the lid gasket Lid lubrication Limit stop adjustment Check tightness of spreader bars Clean safety relief valve As in all food service equipment, the Henny Penny pressure fryer does require care and proper maintenance. The table below provides a summary of scheduled maintenance. Frequency Every 3 to 6 frying cycles As required As required As required Before changing the shortening Daily Daily Weekly Quarterly Quarterly Quarterly Quarterly Annually 3-7. FILTER PUMP MOTOR PROTECTOR- MANUAL RESET The filter pump motor is equipped with a manual reset button, located on the rear of the motor, in case the motor overheats. Wait about 5 minutes before attempting to reset this protective device to allow motor to cool. The filter motor is on the rear of the fryer. It takes some effort to push the reset, and a screwdriver can be used to help reset the button. Electric fryers with serial numbers of HB013JB & below, and gas fryers with serial numbers of GA085JB & below, can push the reset button, by removing the access panel on the left side panel of the unit. To prevent burns caused by splashing shortening, turn the unit s main power switch to the OFF position before resetting the filter pump motor s manual reset protection device

39 3-8. FILTERING OF SHORTENING Frying breaded food requires frequent filtering. Watch the shortening for foaming during frying cycles. Discard the shortening as soon as it shows signs of foaming. Clean the frypot as follows each time the shortening is changed or filtered: 1. Turn main power switch to the OFF position. Remove and clean the fry basket in soap and water. Rinse thoroughly. The best results are obtained when the shortening is filtered at normal frying temperature. 2. Use a metal spatula to scrape any build-up from the sides of the frypot. Do not scrape heating element on electric units, or the curved portion of the gas frypot. Step 2 Scraping the electric fryer elements, or the curved portion of the gas frypot, produces scratches in these surfaces causing breading to stick and burn. Do not bang the pot scraper, or other cleaning utensil, on the frypot rim. Damage to the frypot rim could result and the lid may not seal properly during a cook cycle. The filter drain pan must be as far back under fryer as it will go, and the cover in place. Be sure the hole in the cover lines up with the drain before opening the drain. Failure to follow these instructions causes splashing of shortening and could result in personal injury. Step 4 Surfaces of fryer and basket will be hot. Use care when filtering to avoid getting burned. 3. Open the drain valve very slowly, half a turn at first and then slowly to the full open position. This will prevent excessive splashing of the hot shortening as it drains into the filter drain pan. 4. As the shortening drains from the frypot, use fryer brushes (Henny Penny part number includes both brushes) to clean the side of the frypot and the heating elements (if electric unit). If the drain fills with breading, use the white brush to push the breading into the filter pan

40 3-8. FILTERING OF SHORTENING (Continued) 5. When all of the shortening has drained, scrape or brush the sides and the bottom of the frypot. 6. Rinse the frypot as follows: a. Close the drain valve. b. Open the filter valve. c. Lower lid and hold closed. d. Move the main power switch to the PUMP position. Carefully open the lid to see if the shortening is returning properly. Fill frypot 1/3 full, then turn off pump. FAILURE TO HOLD THE LID CLOSED SO THAT THE FIRST SURGE OF THE RETURNING SHORT- ENING WILL NOT SPLASH OUT OF THE FRYPOT, WILL RESULT IN SEVERE BURNS. Step 6e Step 7a IF THERE ARE AIR BUBBLES COMING UP IN THE SHORTENING, IT S POSSIBLE THAT THE FILTER CONNECTION AT THE UNION ON THE FILTER TUBE IS NOT TIGHTENED PROPERLY. IF SO, TURN OFF THE PUMP AND USE PROTECTIVE CLOTH OR GLOVE WHEN TIGHTENING THE UNION. THIS UNION WILL BE HOT AND SEVERE BURNS COULD RESULT. e. Wash down and scrub the sides of the frypot. Use L brush to clean the heating elements. f. After the sides and bottom are cleaned, open the drain valve. 7. If an optional filter rinse hose is available on your fryer, the following cleaning procedure may be used. a. Attach the filter rinse hose with its quick disconnect fitting to the male fitting inside the door next to the filter valve handle. To do this, slide back the spring ring on the female side of the quick disconnect fitting and let it snap into place over the male half of the fitting

41 3-8. FILTERING OF SHORTENING (Continued) b. While holding the wooden handle, make sure the hose nozzle is pointed down into the bottom of the frypot. Pull the lid down over the nozzle, close the filter valve, and move the main power switch to the PUMP position. Hold nozzle carefully to avoid excessive splashing. Use care to prevent burns caused by splashing of hot shortening. Step 7b c. Rinse the frypot interior. Especially work on hard to clean areas, like the frypot bottom. On electric models clean around heating elements. d. After sufficient rinsing with shortening, close the drain valve. e. Turn the main power switch to the OFF position. Step 7c Step 7f ONLY CONNECT AND DISCONNECT THE FILTER RINSE HOSE WHEN THE MAIN POWER SWITCH IS IN THE OFF POSITION. ALSO, USE A DRY CLOTH OR GLOVE TO AVOID BURNS. FAILURE TO DO THIS COULD RESULT IN SEVERE BURNS FROM HOT SHORTENING SPRAYING FROM THE MALE FITTING. f. Detach the hose. Raise the fitting end of hose high for a minute to allow the remaining shortening in the hose to drain into the frypot. 8. Pump all the shortening out of the filter pan and back into the frypot. Close lid during first surge of pumping

42 3-8. FILTERING OF SHORTENING (Continued) 9. When the pump is pumping air only, the shortening in the frypot will appear to be boiling. Close the filter valve first and then move the main power switch from PUMP to OFF. This will keep the filter pump and lines from filling up with shortening. When bubbling occurs, immediately close the filter valve. This prevents aeration of the shortening, therefore increasing shortening life. Step Check the level of the shortening if necessary, until it reaches the level indicator line on the rear wall of the frypot, or the top level indicator line on model 500s After completing the filtering operation, empty and replace the condensation drain pan. 12. If frying is to be continued at this time, move the main power switch back to the COOK position, and allow time for reheating of the shortening. Step

43 3-9. FILTER PUMP PROBLEM PREVENTION The following steps will help prevent filter pump problems: 1. Make certain the charcoal filter is installed with the smooth side down and the arms on the frame are clamped down over the protrusions on the outside of the frame. 2. The filter valve is to be closed at all times during frying. 3. Pump all the shortening from the filter lines by running the filter pump motor until the shortening in the frypot appears to be bubbling or boiling CHANGING THE FILTER ENVELOPE The filter envelope should be changed after filterings or whenever it becomes clogged with crumbs. Proceed as follows: 1. Move the main power switch to the OFF position. 2. Remove and empty the condensation drain pan. 3. Disconnect the filter union and remove the drain pan from under the frypot. If available, a drain pan may have casters under it, allowing easy transport of filter pan and filter assembly. Step 3 Filter Union This union could be hot! Use protective cloth or glove, or severe burns could result. If the filter pan is moved while full of shortening, use care to prevent splashing, or burns could result. 4. Lift the screen assembly from the drain pan. 5. Wipe the shortening and crumbs from the drain pan. Clean the drain pan with soap and water, then thoroughly rinse with hot water

44 3-10. CHANGING THE FILTER ENVELOPE (Continued) 6. Unthread the suction standpipe from the screen assembly. Step 6 7. Remove the sealer bar and discard the filter envelope. Step 7 8. Clean the top and bottom filter screen with soap and water. Rinse thoroughly with hot water. Be sure that the filter screens, sealer bar, and the suction standpipe are thoroughly dry before assembly of filter envelope as water dissolves the filter paper. 9. Assemble the top filter screen to the bottom filter screen and slide the screens into a new filter envelope. Step

45 3-10. CHANGING THE FILTER ENVELOPE (Continued) 10. Fold the corners in and then double fold the open end. 11. Clamp the envelope in place with the sealer bar. Step Screw on the suction standpipe assembly. 13. Place complete filter screen assembly back into filter drain pan and slide pan back into place beneath the fryer. Step Connect the filter union by hand. Do not use a wrench to tighten. 15. Slide the condensation drain pan back into place. The fryer is now ready to operate

46 3-11. CLEANING THE FRYPOT After the initial installation of the fryer, as well as before every change of shortening, the frypot should be thoroughly cleaned as follows: 1. Turn the main power switch to OFF, and unplug unit from the wall receptacle. Moving either the frypot, or filter pan, while containing hot shortening is not recommended. Hot shortening can splash out. Severe burns could result. The filter drain pan must be as far back under the fryer as it will go, and the cover in place. Be sure the hole in the cover lines up with the drain before opening the drain. Failure to follow these instructions causes splashing of shortening and could result in personal injury. 2. If hot shortening is present in the frypot, it must be drained by slowly opening the drain valve handle one half turn. Leave for a few minutes, then slowly open the valve to the full open position. 3. Close the drain valve and discard the shortening in the filter pan. Then install the filter drain pan under the fryer, leaving out the filter screen assembly. 4. Refer to Wendy s frypot cleaning procedures. DO NOT CLOSE LID WITH WATER AND/OR CLEANER IN FRYPOT. WATER UNDER PRES- SURE BECOMES SUPERHEATED. WHEN LID IS OPENED, ESCAPING WATER AND STEAM WILL RESULT IN SEVERE BURNS

47 3-11. CLEANING THE FRYPOT (Continued) Do not use steel wool, other abrasive cleaners, or cleaners/sanitizers containing chlorine, bromine, iodine, or ammonia chemicals as these will deteriorate the stainless steel material and shorten the life of the unit. Do not use a water jet (pressure sprayer) to clean unit or component damage could result. Make sure the inside of the frypot, the drain valve opening, and all the parts that will come in contact with the new shortening are as dry as possible

48 3-12. CLEANING THE DEADWEIGHT ASSEMBLY At the end of each day, the deadweight assembly valve must be cleaned as follows: DO NOT ATTEMPT TO REMOVE DEADWEIGHT CAP WHILE FRYER IS OPERATING. SEVERE BURNS OR OTHER INJURIES WILL RESULT. 1. Turn the main power switch to the OFF position. Be sure all pressure has been released and open the lid. 2. Unscrew the deadweight cap and remove the cap and dead weight. Deadweight cap may be hot. Use protective cloth or glove, or burns could result. Step 3 Failure to clean the deadweight assembly daily could result in the fryer building too much pressure. Severe injuries and burns could result. 3. Clean the exhaust tube with stainless steel brush (Henny Penny part number 12147). 4. Clean the deadweight cap and weight in hot detergent water. Make certain to thoroughly clean the inside of the valve cap and the deadweight. 5. Clean the deadweight orifice and the inside of the deadweight assembly body with a clean lint-free cloth. 6. Dry the deadweight and deadweight assembly cap. 7. Replace deadweight and deadweight assembly cap. Finger tighten the cap. Step

49 3-13. OPERATING INSTRUC- TIONS FOR OPTIONAL DIRECT-CONNECT SHORTENING SYSTEM 1. Connect the female quick disconnect, that is attached to the hose in the rear of the fryer, to the correct male quick disconnect at the wall. Once attached, the hose can remain connected unless the fryer is moved. Figure 1. In order for the system to work properly, attach the hose to the shortening return line only. 2. Open the drain valve and drop the shortening from the frypot, into the drain pan. Figure 1 3. Once all shortening is gone from frypot, turn the red handle counterclockwise, into the down position and hold. Figure While holding the handle down, turn the COOK/PUMP switch to the PUMP position. Shortening is now pumped from the drain pan. Figure 2 5. Once all the shortening is out of the drain pan, turn the COOK/PUMP switch to the OFF position. 6. Turn red handle back to original position. 7. Frypot is now ready for fresh shortening

50 3-14. REVERSING THE LID GASKET Reversing the lid gasket helps to prevent early failure of lid gasket and the loss of pressure during a cook cycle. 1. Back the 4 lid liner screws (2 on each side) out about 1/2 inch (12.7 mm). 2. Using a thin blade screwdriver pry out the gasket at the corners, and then pull gasket from lid. Check the gasket for any tears or nicks. If the gasket is damaged, it needs to be replaced. 3. Clean the gasket and gasket seat with hot water and cleaning detergent. Rinse with clean hot water. 4. Install the gasket with the good side out and tighten the 4 screws. Install the four corners of the lid gasket. Smooth the gasket into place, working from the corners towards the middle of each side

51 3-15. LID LUBRICATION To extend the life of lid components, lubricate the ball seat and spindle, following the steps below. 1. Close and latch the lid, and turn the spindle counterclockwise until it stops. 2. Press down on the front of the cross bar, pull out the release pin, lift the latch, and raise the cross bar. 3. Using spindle lube (part no ), lubricate the ball seat in the center of the lid cover. 4. Turn spindle clockwise until it stops and then lubricate the threads on the spindle using the spindle lube. 5. Turn the spindle counterclockwise until it stops, line up the lid cover with the cross bar, pull the release pin out, and firmly press the cross bar back into place. 6. The fryer is now ready for use

52 3-16. LIMIT STOP ADJUSTMENT To extend the life of the lid gasket and help prevent steam leakage, check the limit stop adjustment quarterly, following the steps below. 1. Close and latch lid, and turn spindle counterclockwise until it stops. 2. Using a 3/16 Allen wrench, loosen the 2 set screws on the outer collar of the limit stop. Step 2 3. Turn the inner collar clockwise until it stops. Insert a small screwdriver or Allen wrench in the hole in the inner collar to assist you in turning the collar. 4. Turn spindle clockwise until it stops. The lid gasket is now touching the frypot rim. Step 3 5. From the front of the fryer, turn the spindle at least 3/4 of a turn, but not over 1 turn. One of the spindle arms should be lined up with the red ball of the latch, at this time. 6. Slightly turn the spindle past this position, so it should show in about the 7 o clock position. The 7 o clock position is only to allow slight additional turning of the spindle to relieve any side pressure against the locking pin. Side pressure holds the pin in the locked position, even after all the pressure has released. When adjustment is complete, if a black ball on the spindle is lined up with the red ball on the latch, unscrew the black ball and the red ball on the spindle and change places on the spindle. The red ball on the spindle should now line up with the red ball on the latch

53 3-16. LIMIT STOP ADJUSTMENT (Continued) 7. Turn the inner collar counterclockwise until it stops against the bottom hub of the spindle. 8. Tighten Allen screws. If the lid cover fails to seal properly, steam escapes from around the gasket during frying. Readjust the limit stop, this time turning the spindle 1 full turn after the initial contact of the lid gasket with the frypot rim (step 5) CLEANING THE SAFETY RELIEF VALVE DO NOT ATTEMPT TO REMOVE THE SAFETY VALVE WHILE FRYER IS OPERATING, OR SEVERE BURNS OR OTHER INJURIES WILL RESULT. SAFETY VALVE DO NOT DISASSEMBLE OR MODIFY THIS SAFETY RELIEF VALVE. TAMPERING WITH THIS VALVE COULD CAUSE SERIOUS INJURIES AND WILL VOID AGENCY APPROVALS AND APPLI - ANCE WARRANTY. 1. Remove deadweight cap and deadweight. 2. Use a wrench to loosen the valve from the pipe elbow, turn counterclockwise to remove. 3. Clean the inside of the pipe elbow with hot water. Turn the safety relief valve towards the rear of the fryer when reinstalling the relief valve. 4. Immerse the safety relief valve in a soapy water solution for 24 hours. Use a 1 to 1 dilution rate. The valve cannot be disassembled. It is factory preset to open at 14-1/2 pounds of pressure (999 mbar). If it does not open or close, it must be replaced

54 3-18. CHECK & TIGHTEN ELEMENT SPREADER BARS (Model 500 only) To extend the life of the temperature probe, high limit, and elements, every 90 days check the tightness of the element spreader bar screws, following the steps below: Drain shortening and allow fryer to cool before proceeding with the following steps. Surfaces of the fryer will be hot and burns could result. 1. Check that all spreader bars are in place (4 sets), and using a 5/16 socket or wrench, tighten all the element spreader screws. If the bolts or spreaders are missing or damaged, order kit no from your nearest Henny Penny distributor. 2. Pump shortening back into frypot and unit is now ready for use
